“…In other words, the model requires only one material constant to be fully defined, while the elastic behaviour of isotropic materials is defined with two independent material constants. This is a consequence of the assumptions made for the bond-based peridynamic theory (Silling and Askari 2005;Hu et al 2012;Oterkus and Madenci 2012). This limitation has been removed in the state-based peridynamic theory , where the interaction between and depends on the collective behaviour of their neighbouring particles.…”

“…However, the models proposed in (Xu et al 2008) and (Oterkus and Madenci 2012) require a uniform grid of particles and can only be used to model plies with a certain orientation. Hu et al proposed a method to remove these limitations, but it significantly adds to the computational cost for problems that use a non-uniform grid or a uniform grid with an arbitrary orientation of fibres.…”

A new material model for the dynamic fracture analysis of anisotropic materials has been proposed within the framework of the bond-based peridynamic theory. This model enables predicting complex fracture phenomena such as spontaneous crack nucleation and crack branching, curving and arrest, a capability inherited from the bond-based peridynamic theory. An important feature of the model is that the bond properties, i.e. the stiffness constant and critical stretch, are continuous functions of bond orientation in the principal material axes. This facilitates fracture analysis of anisotropic materials with random orientations, such as polycrystalline microstructures. Elastic and fracture behaviour of the model has been verified through simulating uniaxial tension of a composite plate and fracture of a cortical bone compact tension specimen, and making quantitative comparisons to analytical and experimental data. To further demonstrate the capabilities of the proposed model, dynamic fracture of a polycrystalline microstructure (alumina ceramic) has been simulated. The influence of the grain boundary and grain interior fracture energies on the interacting and competing fracture modes of polycrystalline materials, i.e. intergranular and transgranular fracture, has been studied.

Surface oxidation degrades the durability of polymer marix composites operating at high temperatures due to the presence of strong coupling between the thermal oxidation and structural damage evolution. The mechanism of oxidation in polymer matrix composites leads to shrinkage and damage growth. The thermo-oxidative behavior of composites introduces changes in diffusion behavior and mechanical response of the material. This study presents the derivation of peridynamic formulation for the thermo-oxidative behavior of the polymer matrix composites. As a demonstration purposes, isothermal aging of a unidirectional composite lamina is presented by using peridynamics. Oxidation contributed to the damage growth and its propagation.

“…As a result of this procedure, when a polycrystalline system of random texture is represented by this model, type-2 bonds will exist in many different directions according to the random orientations of the crystals. The bond constants for type-1 and type-2 peridynamic bonds can be expressed in terms of the material constants of a cubic crystal, ij C , by following a procedure similar to that explained in (Oterkus and Madenci, 2012). In the case of plane stress condition, the bond constants can be expressed as: 2 2 2 11 11 12 11 12 12 11 1 2 3 11 11 12( ) 4(3 2 ) ,…”

The material is modelled at the microscopic scale using microstructural data. First-principle studies available in the literature are used for characterizing the process of intergranular material strength degradation. The model consists of a polycrystalline AISI 4340 high-strength low-alloy (HSLA) thin, pre-cracked steel plate subjected to a constant displacement controlled loading and exposed to an aqueous solution. Different values of stress intensity factor (SIF) are considered, and the resulting crack propagation speed and branching behaviour are found to be in good agreement with experimental results available in the literature.
